Water Quality Program Recreational Water Monitoring
Long Beach has approximately 7 miles of public beach and is visited by over 50,000 people during the summer months. In order to protect the safety of the public, weekly water samples are collected and tested routinely to monitor bacterial levels. If you would like more information on beach water quality, please call our office between 8 a.m. and 5 p.m, Monday through Friday at (562)570-4134.

Important Note: After any significant rainfall (0.10" or more) high levels of bacteria from storm drains, rivers, and polluted runoff enter our ocean. It is recommended to avoid all ocean water contact for at least 72 hours after rainfall, especially at storm drain outlets, river mouths, streams, and lagoons. People should always pay particular attention to any warning signs posted at the beach for their safety.
